Crystallization behavior of alkoxy-derived cordierite gels
(Springer, New York, 2003)
Alkoxy-derived cordierite gels were synthesized from tetraethylorthosilicate (TEOS), aluminum isopropoxide (Al(OPri)(3)), and magnesium ethoxide (Mg(OEt)(2)). TEOS was partially hydrolyzed at molar ratios H2O/TEOS=1.2, in ...
Sterilized plum pomace biochar as a low-cost effective sorbent of environmental contaminants
(Journal of Water Process Engineering, 2023)
The removal of environmental pollutants is significant because of their harmful effects on living organisms. Biochar is favorable as a natural adsorbent of environmental pollutants due to its advantages, such as environmental ...
Design of biocompatible immobilized Candida rugosa lipase with potential application in food industry
(Wiley-Blackwell, Hoboken, 2016)
BACKGROUNDBiocatalysts are a promising alternative for the production of natural flavor compounds. Candida rugosa lipase (CRL) is a particularly important biocatalyst owing to its remarkable efficiency in both hydrolysis ...
Antioxidant edible films based on chitosan and starch containing polyphenols from thyme extracts
(Elsevier Sci Ltd, Oxford, 2017)
The aim of this study was to analyse the antioxidant activity of different polymeric matrices based on chitosan and starch, incorporating a thyme extract (TE) rich in polyphenols. TE provided the films with remarkable ...
Composite nanostructured hydroxyapatite/yttrium stabilized zirconia dental inserts - The processing and application as dentin substitutes
(Elsevier Sci Ltd, Oxford, 2018)
The objective of the study was to process nano-structured hydroxyapatite/yttrium-stabilized zirconia bioceramic and to investigate the possibilities of its application as dentin replacement in the form of dental inserts. ...
Kinetics and reactor modeling for CaO sorption-enhanced high-temperature water-gas shift (SE-WGS) reaction for hydrogen production
(Elsevier Sci Ltd, Oxford, 2016)
Hydrogen, an important energy carrier of the future, produces no pollution and has a high content of energy. It is formed as a direct product of the water-gas shift (WGS) reaction, which occurs in various processes for the ...
Optical properties of composite restorations influenced by dissimilar dentin restoratives
(Elsevier Sci Ltd, Oxford, 2018)
Objectives. To evaluate optical properties (color and translucency) of 'sandwich' restorations of resin-based composites and esthetically unfavorable dentin restoratives. Methods. Cylindrical 'dentin' specimens (8 mm in ...
Influence of common juniper berries pretreatment on the essential oil yield, chemical composition and extraction kinetics of classical and microwave assisted hydrodistillation
(Elsevier Science Bv, Amsterdam, 2018)
The present paper dealt with the influence of the common juniper berries pretreatment on the yield, chemical composition and extraction kinetics of juniper essential oil (JEO) obtained by classical (HD) and microwave ...
Micro-environmentally restricted cell growth dynamics - modeling considerations
(Taylor & Francis Ltd, Abingdon, 2015)
Various modeling approaches have been applied to describe the rearrangement of immobilized cell clusters within the extracellular matrix. The cell rearrangement has been related with the micro-environmental restrictions ...
Monolithic nanocrystalline SiC ceramics
(Elsevier Sci Ltd, Oxford, 2016)
Additive-free beta-SiC nanopowders were densified by using high-pressure "anvil-type with hollows" apparatus at the pressure of 4 GPa in the range of 1500-1900 degrees C. The starting powder with average particle size of ...
